Summer/winter heating limit
Summer/winter heating limit
The summer/winter heating limit switches the
heating on or off through the year according to the
temperature ratio. Changeover is performed
automatically when in automatic mode and thus
avoids the user having to turn the heating on or off.
Changing the input value makes the respective
annual periods (summer/winter) shorter or longer.
If the value is increased:
-
Changing to winter operating mode is advanced,
changing to summer mode is delayed.
If the value is decreased:
-
Changing to winter mode is delayed; changing to
summer mode is advanced.
Information:
This function does not work in "Continuous comfort
temperature" mode. (Sunlight)
The controller displays "ECO".
The outdoor temperature is attenuated to take the
building's dynamics into account.

Flow temp setpoint min (for fan convectors)

Flow temp setpoint max
This limitation allows to define a range for the
flow temperature setpoint. When flow temperature
setpoint demanded by the heating circuit reaches
the threshold, the setpoint remains permanently at
the maximum or minimum, even if the heat demand
continues to increase or decrease.
Example (line 741 and 1041):
Floor heating system = 50 °C
Higher temperature radiator = 65 °C
